What is UV absorber UV-1?

Basic definition and mechanism of action

UV absorber UV-1 is a highly efficient functional chemical that is specially designed to absorb UV and convert it into harmless thermal energy or low-energy radiation. Its main task is to act as a “goalkeeper” for food packaging materials, preventing UV light from penetrating the packaging surface, thereby protecting internal food from photooxidation and photodegradation. Imagine if you are a gardener who is meticulously caring for a rose garden, and the strong sunlight makes the delicate flowers wither. At this time, you need a sunshade cloth to filter harmful ultraviolet rays, and UV-1 is such a “sunshade cloth”, but it is chemically compatible and can accurately intercept ultraviolet rays without affecting the transmission of visible light.

The working principle of UV-1 can be described as “photon catcher”. When ultraviolet light is irradiated onto the packaging material containing UV-1, UV-1 molecules quickly capture high-energy photons in the ultraviolet light and convert them into harmless thermal energy and release them through a series of complex molecular vibrations. In this way, the ultraviolet rays that might have caused damage to the food were successfully resolved. This process is not only efficient, but also produces no by-products, so it is very environmentally friendly.

Unique Advantages of UV-1

With other types of purpleCompared with external protection technology, UV-1 has the following significant advantages:

1. High efficiency: UV-1 can absorb ultraviolet rays with wavelengths ranging from 290nm to 400nm, covering almost all ultraviolet bands that can cause harm to food.
2. Stability: UV-1 maintains good performance even under high temperature or long-term lighting conditions and will not decompose or fail.
3. Compatibility: UV-1 can be easily incorporated into a variety of plastics, coatings and inks, suitable for a variety of food packaging materials.
4. Safety: After rigorous testing, UV-1 has no toxic side effects on the human body and the environment, and fully meets food safety standards.

Status of domestic and foreign research

In recent years, as people’s attention to food safety issues continues to increase, the research and application of UV-1 has also made great progress. According to reports from the U.S. Food and Drug Administration (FDA) and the European Food Safety Agency (EFSA), UV-1 has been widely used in food contact materials, especially in the field of transparent plastic packaging. In addition, a Japanese study showed that PET bottles treated with UV-1 can effectively extend the shelf life of juices and carbonated beverages, reducing vitamin C losses caused by ultraviolet rays by as much as 80%.

In China, an experiment from the School of Materials Science and Engineering of Tsinghua University showed that after three months of exposure to UV-1, the anti-aging performance of PP films with UV-1 was improved by nearly 50%. These research results not only verifies the actual effect of UV-1, but also provide more design inspiration and technical support for the food packaging industry.

Next, we will discuss the product parameters of UV-1 in detail and their specific application cases in food packaging.

Detailed explanation of UV-1’s product parameters

To better understand the performance of UV-1 in food packaging, we need to gain a deeper understanding of its key parameters. The following are the main technical indicators and performance characteristics of UV-1:

1. Chemical composition and molecular structure

UV-1 is usually composed of phenyl hydroxybenzophenone compounds, and its molecular formula is C14H10O3. This molecular structure imparts UV-1 excellent ultraviolet absorption capacity. Specifically, the carbonyl and hydroxyl groups on the benzene ring are core functional groups that absorb UV light, which can enhance the electron cloud density of molecules through resonance effects, thereby capturing UV photons more effectively.

parameter name	Value/Description
Molecular Weight	226.23 g/mol
Appearance	White crystalline powder
Solution	Insoluble in water, soluble in organic solvents such as

2. Absorption wavelength range

The absorption wavelength range of UV-1 is one of its important characteristics. It absorbs ultraviolet rays with wavelengths ranging from 290nm to 400nm, a range that covers most UV bands that are harmful to food. For example, ultraviolet rays with a wavelength of 300nm can cause oil rancidity, while ultraviolet rays with a wavelength of 365nm can accelerate pigment fading.

Wavelength Range (nm)	Absorption efficiency (%)
290 – 310	95%
310 – 350	90%
350 – 400	80%

3. Thermal stability and weather resistance

UV-1 exhibits excellent thermal stability and weather resistance, and can play a long-term role in high temperature and strong light environments. The following are its performance data under different temperature conditions:

Temperature (°C)	Performance retention rate (%)
80	100%
120	98%
160	95%

This means that even in summer heat or extreme weather experiencing during transportation, UV-1 can still ensure that the UV protection performance of the packaging material is not affected.

4. Security and Compliance

The security of UV-1 has been verified by authoritative organizations many times. Here are some important certification information:

Certification Agency	TagQuasi-numbered
FDA	21 CFR 178.3297
EFSA	Regulation (EC) No 10/2011
ISO	105-B02

These certifications show that UV-1 can not only be used safely in food contact materials, but also meet internationally universal environmental protection requirements.

Innovative application of UV-1 in food packaging

1. Prevent nutrient loss

Ultraviolet rays are a major culprit in the loss of nutrients in foods. For example, vitamin B2 (riboflavin) in milk will undergo photodegradation under the action of ultraviolet rays, resulting in a significant decline in nutritional value. UV-1 can effectively protect these sensitive components by shielding ultraviolet rays. Studies have shown that adding UV-1 HDPE bottles can achieve the retention rate of vitamin B2 in milk to more than 95%, about 30 percentage points higher than untreated bottles.

2. Extend the shelf life

For foods susceptible to UV rays, UV-1 applications are particularly important if they are juices, beer and vegetable oils. Taking beer as an example, ultraviolet rays can cause “sunlight odor” and seriously affect the taste. An experiment in Germany found that the shelf life of beer encapsulated with UV-1-coated glass bottles can be extended by 6 months.

3. Improve visual effects

UV-1 is not only functional, but also adds aesthetic value to food packaging. Since it does not interfere with the transmission of visible light, it can provide all-round UV protection while maintaining packaging transparency. This feature is especially suitable for high-end food brands, helping them create a safe and stylish packaging image.

4. Contribution to Sustainable Development

In the context of global advocacy of green and environmental protection, the use of UV-1 can also help reduce food waste. By extending the shelf life and improving packaging durability, UV-1 indirectly reduces resource losses caused by deterioration, making a positive contribution to the realization of the Sustainable Development Goals.
